More are picked up over by the front of terminus (5)
I believe the answer is:
extra
'more' is the definition.
(thesaurus)
'are picked up over by the front of terminus' is the wordplay.
'picked up' says the letters should be written in reverse.
'over' is an insertion indicator.
'by' becomes 'x' (multiplication sign**).
'the front of' indicates taking the first letters.
The initial letter of 'terminus' is 't'.
'are' backwards is 'era'.
'x'+'t'='xt'
'era' placed around 'xt' is 'EXTRA'.
(Other definitions for extra that I've seen before include "on top" , "eg Wide; additional" , "small-time actor" , "additional supplies" , "Actor in crowd scene, no lines" .)
